LOCKING DEVICE.

ToaZZwwmit mag/concern:

-Be it known that I, ARTHUR, rREGINALD COLLIER, .asubject of the King4of Great Bri-tain and Ireland residing' at '64 Brownlowiload, NewSouthgate, MiddleseX,"Eng-. land, .have invented rnew and `usefulImproveniente in4 and Relating' to Locking Devices, of-.which the'following-is a specifi cation. i

My Yinvention yrelates to fa lock, operated from a common centre, forsecuring a door (ar-.the like lat three or more places, and designed foruse on the outside doors of private houses, dilate, shops, warehouses,churches, kgarages and other places liable to bede-,tt -at times withoutan occupant. The invention is also applicable for use on the doorsof-strong-rooms, store-rooms and the like.

`Broadly stated the invention comprises a lockffor securing a door orthe like at three or more points, which when secured by the turrringof ahandle yor knob. on the outside of the door can only be` operatedfronrthe outside by means of a key and cannot be operated from theinside by any means.

According to the 'invention' a horizontal sliding bolt is adapted tonormally project in front of the lock case and bevelled or rounded Aonone side of the projecting' end in the ormof an ordinary latch bolt.This latch bolt is combined with an'inner horizontally sliding membercontained entirelyV within the lock case and'two or more verticallysliding` bolts respectively adapted to engage when moved to the lockingposition in .staples or boxes arranged in the door frame above and belowthe door.

The combination of bolts is operated and controlled.` by a key andinside and outside knobs or handles and is so arranged 'that by closingthe :door and turning a knob ont the outside of the door, itis securedin three or more .places and cannot be opened by any means Yfrom inside,and only by the use of the key Jfrom the outside. Thile by closing thedoor and turning the knob on the inside and by securingthe verticalbolts at top and bottomby additional locking means the door is securedin three or more places and cannot be opened'from the outside by anymeans, but can be opened from inside by first releasing the verticalbolts at top and bottom and then turning the knob or handle. Whentheivertical bolts are drawn and the lock is in normal on the latchposition,

the door may be freely opened from both `inside'and .outside by turningthe knob but the verticalbolts cannot be operated.

The invention is illustrated byway of example in the yaccompanyingdrawings, `in which- 'Y i Figure 'l shows thelock 'with its parts in thelnormal on the latchL position with the vertical bolts drawn.

EFigure 15 shows an alternative form. of the actuating cam on the insidemember of the ,divided spindle.

Referring now to the vrdrawings a pair of vertically sliding bolts l(Figure 6) are operated from one or both sides oi the door by means ofknobs or handles 2 fixed u on a divided spindle (Figure 9) and when s otengage in staples 3 as shown. or boXes or the like fixed on the doorframe 4 or in recesses provided in 'the same. The divided spindle whichis shown in detail in Figures 7 and 8 is employed to allow the innerknob or handle to be turned to a certain distance to draw the latch bolt5 when the outer knob or handle is locked by cam 6 on its part of thespindle engaging the butt end of a stop 7 and thus preventing furthermovement of the cam 6 until the stop is lifted, shown in Figure 1. rlhehorizontally sliding latch bolt 5 assumes a latching or halt' throwposition limited by a removable stop 45 or a full thrown or lockingposition when said stop is removed due to projection by its spring 9engaging the lug 90 carried by the said bolt 5. Slidably nested on thelatch bolt is a plate or inner bolt member 8 carrying a lug 18 andprojectable by a spring 10 engaging another lug 100 carried by the saidmember 8 to move the lug 18 into a notch 19 in vertical bolt 1 when saidbolt is moved to locking position to bring notch 19 in registration withlug 18. The inner bolt member 8 is operated by means ot a suitable keyspindle 11 fitted with suitable operating means such as 'cams 12 (asshown), cogs, spokes or the like engaging with correspondingl cammembers 13 projecting from the wall ot a central recess 14 in the saidsliding member 8. This key spindle 11 is adapted to be turned from theoutside of the door by the key only. The key operated gear itself formsno part of this invention and may be ot any suitable form. convenientfor the thickness of the door on which the lock is mounted. The portionoit the dividedv spindle (Figure 7 connected directly with the outsidehandle operating the vertically sliding bolt 1 is fitted with cams 15 asshown, or cogs, spokes or the like, so arranged that when the spindle isturned by a knob or handle trom the inside or outside ot the door thecam members 15 engage in correspondingly shaped recesses 16 on the sidesot the vertical bolts, and cause said bolts to travel in oppositedirections, As shown in Figure 3 one ot these vertically sliding bolts 1is so Jformed that when in the withdrawn position a shoulder 17 thereonengages with a shoulder 18, Figure 5, on the key operated hori- Zontallysliding member 8 and holds the latter in position against its spring 10.Upon turning the outer handle or knob in order to shoot the verticalbolts, the bolt 1 with thev shoulder 17 travels to a position in which arecess 19 therein is in alignment with the shoulder 18 of the keyoperated sliding member 8 thus allowing the same to move forward underthe iniiuence ot its spring 10 and its shoulder 18 to pass into saidrecess 19 and to hold the vertical bolt and consequently the oppositevertical bolt 1 firmly locked against operation by the cams 15 mountedon the divided handle spindle. When the bolts 1 are thus shot the dooris secured at the top and bottom and at the side by the latch bolt 5 andcan only be opened by the use ot a key :trom the outside to turn thespindle 11 through which the sliding member 8 can be withdrawn to aposition in which the shoulder 18 is clear oi' the recess 19l in theupper vertical bolt.

-The channel 4() above the shoulder 17 in the bolt 1 receives the flange41 of the latch bolt 5, (Figures 1 and This iiange 41 normally rests inthis channel when the latch bolt is in the on the latch position and soprevents the bolts 1 trom being shot until theA sleeve portion of aspring controlled vertical stop 24 has been withdrawn from the latchbolt 5 on the inside ot the door by the person opening the door throughan actuating arm 42 outside the lock casing.

lThe crank projection G on the portion directly 4connected with theoutside handle of the divided spindle engages in the V between themembers 20 and 21 of the inside portion as shown in Figure 9. Thesemembers 20, 21 are arranged so iar apart that when the spindle connectedwith the outside handle has been revolved beyond the point necessary towithdraw the vertical bolts 1 the inside part ot the spindle (Figure 8)can still be turned a suiiicient distance in said V ttor its cam member22 to engage the end o't the lever arm 23 which is in alignment with thesliding latch bolt 5 and to withdraw the saine against the iniiuenrc otthe spring 9 to aposition in which it is clear ot the box on the doortrame. Then the outside handle is turned to withdraw the bolts theprojection 6 on the outside part ot' the spindle is adapted to litt thevertical spring` controlled stop 45 into engagement in recess 25 in thesliding member 8 and the latch bolt and thus holds both in their normalpositions in the lock casing, with their springs 9 and 10 partiallycompressed. This double stop formed by the pin 24 and sleeve 45, and thecrank 6, is lurther controlled by an outdoor latch stop 7 best seen'inFigure 4. rPhe stop slides in a boss 48; it has a head 27 by which itmay be withdrawn trom inside the door against the action out a spring 49compressed between the end of the boss and the transverse pin 50 in thestop; this pin further engages a groove 51, shown as a spiral groove inFigure 4, and so serves to retain the stop in inoperative positionagainst the action ol the spring.

The action ot the apparatus may be seen trom Figures 1, 2 and 5.

1n Figure 1 the parts tre shown in the indoor latch position. The bolts1 are withdrawn, the Vtlairge 41 is engaged in the recess 40 ot theupper bolt and so prevents the bolts being shot. lt either handle isturned the latch cam 22 will rotate the lever and partially withdraw thelatch bolt 5. Betere it fully withdrawn the crank (i abuts upon theout-door latch stop 7 and the outdoor handle cani be no iurtherlturned;

hence the door cannot be opened from outside. .But on account .of thelost motion between the crank 6 andthe V 20, 2l, `the indoor handle canbe turned a little further, suiiiciently nto 4withdraw the .latch bolt 5wholly from its socket.

It the stop 7. is withdrawn by rotating the head 27. there is noobstacle to movement of the cam; 6; except'the .offset portion of thestop 24; moreover, this stop can be lifted by the crank .against theaction of spring 46. 1n this condition, therefore, the-latch can. bewithdrawn from indoors or outdoors. V

If; the partsare in the indoor latch position and the occupant .proposesto leave the house `torsorne time, .and desiresV to .leave it safelylocked, .his iirst action is to pull down the fingerlpiece 42,Y sowithdrawing 'the latch bolt stop 45 fromitheslot 2,55. The spring 9'being `already in compression will thrust forward: the latch boltsutiiciently to carry the lange 41 .out `oi? the slot40 of bolt l. Thebolts-arethenfree to be shot. Next the stop 7 `is withdrawn; thecompressed spring 46 at once thrusts down the stop 24, so withdrawingitfrom the; recess 25 4in the member S. Theoccupant then leaves the house,closes the door and shoots the bolts 1, by rotating the outdoor. handle.As soon as the recess 19 in the upper bolt comes opposite the shoulder18oi the member 8 the member will move :forward under. the action of.itsspring 10. and engage the shoulder in the recess. Thus the bolts arelocked in shot position. Thisl occupant absent condition is shown inFigure 2. .The door .cannot now be opened Ytrom inside at all, .and can.only be opened from outside by the use of the proper key. To open `itthe spindle 11 is turned by the aid ot the key, so that the cams or lugs12 withdraw the member 3 against the action oi spring 10. When it hasmoved so far that the shoulder 18 is clear `of the upper bolt the twovertical volts can be withdrawn by rot-atingf'the` outdoor handle. Atthe end of this motion. the cam 22 engages the lever 23 and-withdrawsthe latch. There is no obstacle to the passage of crankv 6 except theol'fsetpart of `the stop 24'; and since member 8 has been withdrawn sothat its recess handle. As a iinal security to prevent the bolts beingwithdrawn from outdoors he engages lthe hinged members 30 with the slots31 in the `bolt-s. -This is the occupant within condition. In Figure 15I show an alternative form of the cam 6 which enables the outside handleto be lockedirom movement in either directionby means ofthe stop?. Inthisform a curved recess 43 is provided in the engaging face of the cam6 adapted vto receive. the stop 7. This curved...recess.43.is deepenough-tor its extremity 44 to engage the stop ran'dyto prevent theoutside handle iromubeing turned in either ldirection lwhen thestop isin. position in said recess. `The stop 7 can be put "out `of actionl.to'enable the door to be openedby the .outside .handle .2 from the onthe latch position. Any su-itable means may be employed to retain thisstop 7. in the free position out off-action such for instance, as shownin= Figure 13, infwhich aflateral pin 28 can .bearranged to engage inabayonet channel cut in `thewafll :ofthe sleeve 29 enclosing the stopand operating spring.y When the door is lbolted from the inside, thevertical Abolt can-.befurther securediat the topand bottom of thedoor-.by a

hinged member 3() on the .braclet132 adapt-ted l to engage in one .orother. of. the-*recesses 3l at the extremities of the bolts 1.' Thebracket 32 is fixed in a suitable position vto the face of the idoorandthe member'BO is adapted to engage the upper recess 31 .whenr'theboltlis in the withdrawn position and thelower recess when the `bolt hasbeen shot. Anyequivalent ldevice can be used.

In'lzigure 141 show Ian alternative 'form offlock for use -in premisessuch asdwelling houses in which itis convenient Y' tofallow oi the-innerslidingmember `Shaving a longer rearward travel the recess 25 :and sloty255 being elongated 'for this purpose, so` as to admit of the completewithdrawal of the latch rbolt 5 by the key alone when the latter is inthe on'theylatch or normal position. .This arrangement allows of thehouse being entered byv more than 4one person provided with duplicatekeys. Intl? igures 11 and 12 Ishow by way of example two methodsofsecuring a Idoor` at more than three places. In Figure 11-1 show twoviews in whichV one or more additional sliding bolts 35 are slidinglyfixed on the side ot' the door and are operated bythe curved part '36 ofthe vertical iboltil which nirved part operates said 4bolt 35 throughthe pins 37. In the upper 7figure the bolt35 is shown withdrawn while'in thev lowery .figure it is shown in engagement with fthe staple38 onthe-door `frame. In the alternative form l'shown in Figure 12 the bolts35- are pivoted to the vertical bolts 1Jand to the ydoor at 39Y so thatas said bolts 1 rise and fall the bolts 36 are shot or withdrawn siO'nalfashion.
